In a small bowl, whisk together the tamari, rice vinegar, minced fresh ginger, and minced garlic to create the stir-fry sauce.
Heat the toasted sesame oil in a large non-stick skillet or wok over medium-high heat.
Add the broccoli florets to the pan with a small splash of water, then cover with a lid for 2 minutes to steam until they are vibrant green.
Remove the lid and stir in the shelled edamame and red pepper flakes, sautéing for another 2 minutes until the broccoli is tender-crisp.
Carefully add the silken tofu to the skillet, using a wooden spoon to gently break the block into large, bite-sized chunks.
Pour the prepared sauce over the tofu and vegetables, then sprinkle the nutritional yeast evenly across the pan.
Gently fold the ingredients together for 1 minute, being careful not to over-mix the delicate tofu, until everything is heated through.
Transfer the stir-fry to a bowl and finish by garnishing with the hemp seeds for added texture and nutrients.
